J Thisinvention relates to a reconditioner orv in the'so-called dry-cleaning of clothing, other fabrics and the like, although capable of general use as a filter and storage tank.

A prime object is to provide a construction which will particularly coact with a .conventional washing machine of the centrifugal type in which a hydrocarbon dry-cleaning agentis used instead. of water and a detergent, to constitute a drycleaning plant in treating thev clothes or goods of which machine the pump returnsith-e"cleaning agent to the unit for cleansing andreuse, and furtherto form a plant in which thedry-cleanly and expeditiously without resort to frequent changing of the cleaning agent.

Another important" object is to "provide an exceedingly compact unitary filter and storage tank to particularly coact with the aforesaid centrifugal I washing machine or the equivalent, to produce a relatively small drycleaning plant having minimum fire-hazard and sea oable of inexpensive installation in relative y small mercantile establishments such as now-iron and-press clothes but which find it necessary, due to the very expensive present day cleaningequipment, to send the clothes or goods if to be first dry-cleaned, to a central drycleaning-plant.

Themor'e specific obj ects and advantages will become apparent and in part will be pointed out in the: description following,

- taken in connection with the accompanying side elevation of the imviewtaken through the unit at a right angle 1 to Fig. 2. i g

I Referring specifically to the drawing, 10

designates a tank or container of any appropriate capacity, which has a bottom wall at 11, and a top wall at 12. Legs 13 or other supporting means are attached to or provided'for the container or tank 10. i

In axial alinei'nent with the tanklO and disposed below the same and fastened there to is a purifying chamberin' the form of acone Disposed completely across the chamber 14 and extendlng downwardlyfrom thewall 11 and terminatingrelatively close'to the apex of the chamber l lis an imperforate baflle wall 15." The chamber ll-is adapted to contain any preferred agent for-cleaning a hydrocarbon as used in the'dry-cleaning'of clothes or other fabrics. 'To this end, chamber 14 may contain a solution of caustic soda to a level above the lower edge'of baffle Wall 15, and for instan'ceto the level 16. The caustic soda solution may also contain charcoal.

The previously mentioned hydrocarbon agent is. directed to the chamber l i througha pipe or conduit 17 which is located within the tank 10, and preferably extends above the top 12thereof, so that it may be connected with a centrifugal drier or extractor of a washing machine, containing the dry-cleaning agent, rather'than water. The pump of such a washing machine torces the cleaning agent through the pipe 17 and since it communicatesthrough the wall llwith the chamber 14', such dry-cleaning agent is dischar ed into the latter. Said drygcleaning agent is caused to pass downwardly through the caustic soda solution in chamber 1 across the lower end of the baflle 15-and thence, up-f wardly through the caustic soda solution on the opposite side of the battle, bubbling through said solution. and into a pipe 18 which communicates through the wall 11 with thechamber 14a, r i

Eccentrically disposed within'the tank or container 10 is a bath cylinder 19 which rests on the wall 11 and is of a heighth to extend above the wall 12. Said pipe 18 is of inverted U-shape and has its outlet end communicating with: the base of the cylinder 19. Thus the cleaning agent whichbubbles' through a the caustic soda solution passes through pipe 18 and thence into the bottom of the cylinder The lower portion of such cylinder 19 7 contains a quantityoi." water to the level shown at 20. In order to soften-the water,

sign matter are. removed.

- and which space serves for the storage of the dry-cleaning agent until it'is. re-used.

A perforated baflle or plate '21 is located within the cylinder 19 above the water, and the same supports a quantity of cotton waste, cotton seed hulls, or thelike, as at 22.

' As the cleaning agentpassesthrough the.

Su ch dry-cleaning agent in the space Qt'is preferably disposedat an elevationhigher than the point of its useiand hence it is adapted to be supplied from the space 24 by gravity through a valve-controlled outletQSa-nd for is instance to a centrifugal type washing machine.

Tank 10 maybe replenished with cleaning agent througl a suitable filling opening, as r at 26,. in the wall 12. The materials for the cylinder 19. may be placed therein when a closure 27, at the topthereof, is'reinoved, such cover'being detachably bolted to thecylinder as at 28. p g 19, a valvecontrolled outlet 29 is provided,

s the same extending from the bottom of'said cylinder outwardly through the container 10 adjacentthe base of the latter.

A valve controlled draining connection 30 may be provided at the apex of'the chamber 7 4, and a filling opening and closurefor such chamber-14 may be used as at 31. 7

- If desired, a sight gauge 33 of conventional form, as well-as other approved accessories,

7 may be used in connection with the tank or container 10, to permit the quantity of the cleaning agent; in the container to be deter- BERG Cl. h v

As a result of the construction described,

anflexceedingly compact arrangement ofa unit affording both afilte r and a storagecontrainer is afforded, whichenables continuous use ofthe cleaning agent, a relatively small quantity thereof to be used at time and the cleaning action to be expeditiously and relatively inexpensive. Such a construction provides a. unit for coaction with a centrifugal type washing machine orthe like, which will enable av dry-cleaning plant tobefproduced atlsuchlow .cost'as to permit installation thereof in mercantile establishmentsfinding present equipment .and necessary solvent too expensive to do their own dry-cleaningand 9 g which causes them to send materials for dryprime consideration, and it further provides such an apparatus as does not'uuduly thwart the inotionof the cleaning agent through the action of the p ump oftho washing machine. 7

While I have described the operation of the apparatus in connection with the" dry-clean ing agent for clothing or the like, it is to'be understood that no limitationtosuch useis to be implied since the invention may be used as a unitary filter and storage tank in various relations. p
